FRICTION-HINGE.

SPECIFICATION forming part of Letters Patent No. 347,124-, dated August l0, 1886.

Application filed December 9, 1885. Serial No. 185,146. A (No model.)

To all whom it may concern.-

Be it known that I, CHARLES P. OUDIN, of the city, county, and State of New York, have invented a new and useful Friction-Hinge, of

-which the following is a specification, reference being had to the accompanying drawings, in whiohe -Figure l is a perspective view of my improved hinge, and Fig. 2 a, section of the same through the knuckles and pintle.

My invention consists in the construction and arrangement of parts, as will be hereinvafter fully described and claimed.

The two leaves b b of the hinge are of the vordinary construction, each leaf having in the present instancetwo knuckles. Within the knuckles is placed a tubular pintle, d, which is of less length than the combined lengths of the several knuckles. The pintle is interior] y screw-threaded at both ends, and into these screw-threaded ends are passed the screws cc,

the heads of which bear on the outer ends of the outer knuckles,so that by tightening either screw the heads of both screws will be pressed jecting from their adjacent edges through aligned apertures, in which rods were passed. A tube was tted on the rod between the upper and lower collars, and the ends of the rods were screw-threaded and provided with nuts, by means of which more or less friction could be produced between the collars; and I ain also aware that the knuckles of a hinge have 'been connected by a tubular pintle having a daring head at one end, a flaring socket at the other end, and interiorly screw-threaded between its ends. The apertures of the outer knuckles were countersunk to receive the head of the pintle and the head of a screw fitting into the socketed end of the pintle. A headless locking-screw was screwed into the interior screw-threaded part of the pintle to lock the headed screw in place` and-I do not claim the said construction as of my invention.

Having thus described myinvention,what I claim as new, and desire to Vsecure by Letters Patent, is- A friction-hinge consisting of the leaves b b, having knuckles, the tubular pintle, screwthreaded interiorly at its ends, fitting Within the knuckles, and of less length than the combined lengths of said knuckles, and the screws c vc, engaging the said screw-threaded ends of the pintle, and bearing with their heads against the outer knuckles, substantially as set forth.
